Values of each group are presented as an average (standard deviation). ^aF-Ex: Group performed five sets of standing back extension exercise after performing the task to fatigue the lumbodorsal muscles. ^bnF-Ex: Group performed five sets of standing back extension exercise without performing the task to fatigue the lumbodorsal muscles. ^cF-nEx: Group remained standing for the same duration as the F-Ex group without performing standing back extension exercise after the task to fatigue the lumbodorsal muscles. ^dBMI: body mass index.
